This magazine as prefexhausted shuttle to enter the auxiliarycell erably constructed comprises a shaft 2, havon the return shot. ingon it a rotatable drum 3, provided with Another important feature of theinvencells 3 for the filled shuttles S, said drum be- 100 tion residesin the weft-holderin the shuttle, ing inclosed in a fixed cylindricalcasing 4, wherein the partial denudation of the weft which keeps theshuttles from falling out of the holders 3 This casing has at its underside a shuttle-pocket 5, into which falls the shuttle from the lowestcell of the drum 3 and from which the fresh shuttle is taken by theshifting shuttle-box B. This pocket 5 occupies a position directly overand above the box B when the lay L is in its beating-up position (seenin Fig. 1) and is open at the side facing the lay. The drum 3, carryingthe shuttles, rotates intermittently, being actuated at proper times bythe receding movement of the lay, and at each movement it brings a cell3 over the pocket 5, so that the shuttle may fall from the cell into thepocket.

The construction of the compound shuttlebox B and of the shiftingmechanism for elevating and depressing it will now be described.

The box B consists of an upper or working cell 6 and a lower auxiliarycell o These cells are best seen in the detached view, Fig. 6. The box Bis guided in its vertical shifting movements in a bracketframe 7 on thelay L and is fixed on the upper extremity of a stem 5, which latter hasa sliding bearing in a bracket 9, fixed on and moving with the lay.There will be, by preference, a spring 10 on the stem 8, which tends todraw down or depress the box B and assist gravityin this respect; butthe weight of the parts may be relied on to effect the depression.

To elevate the box B at the proper times and during the advancingmovements of the lay andto support it in its elevated position duringthe next receding movement of the lay, any suitable means may beemployed. That herein shown will now be described.

On the loom-frame F at the proper point is mounted and fixed a cam-plateO, and on the stem 8 is mounted an electromagnet 11, having its armature12 mounted on the horizontal arm of an L-shaped armature-lever 13, thependent arm 14 of which carries a stud or roller 15. Normally in theordinaryoperation of the loom the compound box B is depressed, the upperbox or cell 6 thereof is alined with the race, and the end of the roller15 plays as the lay vibrates near to but not in contact with the face ofthe fixed cam-plate C; but when the electromagnet ll is excited by thecompletion of the operating-circuit in a manner to be hereinafterdescribed the armature 12 will be attracted and the lever thereofrocked, so that on the forward or beating-up stroke of the lay theroller 15 will be projected so as to engage the inclined camway c, Fig.5, on the plate C and will be caused to ride or roll up said inclinedway, thus elevating the compound box B. After rising -the roller 15 willroll along and be upheld by B move in and wipe over the said shuttle,eugaging it sufficiently to draw the shuttle laterally from the pocket 5when the lay recedes. During this receding movement of the lay theroller 15 travels back along the trackway 0 until the lay nears the endof its receding movement, when said roller drops off from a slightcam-shoulder 0' onto a continuation c of the track c At the end of thereceding movement of the lay the exhausted shuttle S in the oppositeshuttle-box E is shot across into the lower cell 6 of the box B. The laynew advances again, and when the roller 15 impinges on the cam-shoulderc it rides off the trackway and the shuttle-box B falls or is depressed.

It may be explained here that in order to insure the roller 15 beingheld in place on the camway and trackways of the plate C said roller isconed, as seen in Fig. 3, being largest at its outer end, and the camwayand trackways are beveled, as clearly shown in the several views, so asto cause the roller to hook over and keep its place, and it may also bestated that when the exhausted shuttle S leaves the box B theoperating-circuit will be broken, so that when the inclined camshouldera rides or cams the roller 15 off from the trackway said roller willclear the catnplate C, as at first.

Mounted on the bracket 7, in which the box B is guided, is aspring-swell 17, such as is commonly employed on shuttle-boxes. Thisswell is so situated on the bracket 7 that it comes into play with thatcell in the box which is alined with the shuttle-race, or, in otherwords, it is so placed as to act in connection with the upper or workingcell 6 normally; but when the box B is elevated it operates inconnection with the auxiliary cell 0 Thus when the working cell istaking a shuttle from the magazine, as in Fig. 2, the swell will bebelow, leaving that side of the upper cell 6 open, and when the box B isdepressed the side of the cell 6 will be left open, so that on the nextreceding movement of the lay the exhausted shuttle may be discarded andthrown out from this cell into any suitable receptacle 18 on the.loom-frame. It should be understood that the swell 17 and the pickerp donot shift or move up and down with the box B, but only move to and frowith the lay. The bottom 6 of the cell 6 of the box B may be made wavyor toothed, as indicated in Fig. 6, and the bottom of the pocket 5correspondingly cut to match, so that when said cell and pocket closetogether, as in Fig. 2, there may be no collision of the parts.

The drum of the magazine M is rotated by the receding movement of thelay L after a fresh shuttle S has been taken into the working cell (i ofthe elevated box l3 and rotated to an extent sulficient to bring thenext cell 3 into coincidence with the pocket 5, so that the shuttle insaid cell may drop into the now empty pocket. The means for effectingthis partial and intermittent rotation of the drum 3 will now bedescribed with especial refer ence to Figs. 1, 2, and 7. As hereinshown, the drum 3 contains twelve cells 3 and it is intermittentlyrotated one-twelfth of a revolution at each impulse. On the end of thedrum are twelve equally-spaced pins or studs 19, and on the box B is aspring-tappet 20, which normally or when the box is depressed playsunder the lower stud of the concentric series; but when the box B iselevated on the advancing or beating-up stroke of the lay this tappet 2Ostrikes the said lower pin or stud on the drum, then yields and wipespast it by a well-known construction, and finally takes in front of it.When the lay next recedes, the tappet turns the drum by engagement withthe pin to the desired extent and finally passes said pin. To steady thedrum and determine its extent of rotation, a device is employed whichmay be seen at the left in Fig. 3. This device consists of a disk 21,with twelve radial V-shaped teeth fixed on the rotating drum, and amatching disk 21 held up in yielding engagement with the disk 21 byaspring 21, the disk 2l being held against rotation, as by a guide'rod21 in the bracket, on which rod said disk slides when it yields.

Referring now particularly to Figs. 8 to 11, the electrical controllingdevices which we prefer will be described. Fig. 8 shows in sideelevation the shuttle-box B at the opposite side of the loom from thebox 13. This box B may, for the purposes of our invention, be of anyknown kind. S represents, for example, an exhausted shuttle in said boxin Fig. 8. On the box B are two spring-terminals t and t of an outerelectric circuit or partial circuit to tu including a generator C andthe coils of the electromagnetll. When a shuttle is in the box B thespring-terminals on the box are adapted to be put into electricalcontact, respectively, with metal plates m and 'm on the shuttle, theselatter forming terminals of an electric circuit or partial circuitwithin the shuttle, thus closing the two partial circuits into one.Figs. 9 and 10 show the construction within the shuttle. In the shuttleis hinged a spindle 22, which may be of metal, and on this spindle isslipped a cop 23, composed wholly of weft and known as an all cop. Itmay properly be explained here that in forming an all cop the weftthread or filling is wound on a smooth spindle,'and when complete thecop or mass of weft is slipped off the spindle. The latter leaves aclear hole or bore in the cop, and when it is to be placed in theshuttle the weaver simply slips it onto the spindle therein, asindicated in Figs. 9 and 10. Fig. 11 shows the all cop detached. Thespindle 22 is hollow at its butt and has fitted in it a tube 24, ofinsulating material, slotted at its'inner end coincident with a slot oraperture in the wall of the spindle. Within the tube 24 is a metalterminal spring 25, which has a bend that tends to project out throughthe aperture in the spindle 22, and thus allow the free end of theterminal 25 to come into contact with the metal spindle. When the cop 23is slipped onto the spindle, as in Fig. 9, the bend in the terminal 25projects through a slot in the spindle and bears on the overwrapped weftcovering the whole or a part of said slot or aperture, whereby saidoverwrapped weft maintains orholds the terminal 25 out of metalliccontact with the spindle 22. The terminal 25 is connected electricallyby a suitable conductor 26 with the terminal plate m on the shuttle, andthe spindle 22 is similarly connected by a suitable conductor 26 withthe plate m Thus it will be seen that normally with a full cop the weftwill maintain a break in the partial circuit in the shuttle; but if theWeft be exhausted to an extent sufficient to permit the terminal 25 tospring outward into contact with the metal spindle or with metal on thespindle, if the latter be not itself of metal, the circuit will beclosed in the shuttle. Under these circumstances when such an exhaustedshuttle enters the shuttle-box B the contact of the terminals 25 and 25with the plates m and m will complete the circuit through the magnet 11.

Respecting the magazine M, it may be said that the size of the drum 3 isonly limited by practicability of construction. The cells 3 are filled,primarily, at a gate or door at 4* in the casing 4. This gate may be atany point. In Figs. 1 and 2 (where part of the magazine is broken away)it appears at the side and in Fig. 7 it is at the top. There is a slideor slides at to interpose between the drum and the pocket 5 temporarilywhile filling the cells 3 and the drum is rotated intermittently by handto bring the cells consecutively to the filling opening or door. Thedotted lines in Fig. 2 show the lay in its receded position. It is notessential nor desirable that the casing 4; shall wholly cover and hidethe cells 3 It may be sufficiently open to enable the weaver to notewhether all of the cells 3 are full or not. The purpose of this casingis merely to keep the shuttles from being thrown out of the cells in thedrum 3. Any suitable provision may be made for filling the cells in thedrum with filled shuttles.

Where the spindle 22 in the shuttle is not of metal, a metalcontact-piece 22 may be set therein, as represented in the fragmentarysectional view, Fig. 12, which shows the spindle denuded of weft.

Fig. 13 shows a slightly-modified form of the spring registering deviceseen at the left in Fig. 3 for holding the drum 3 against too easyrotation. In this construction a springfinger 21, fixed on the bracket1, engages the teeth of the disk 21 on the drum, said finger having anaperture to permit the passage of the journal of the drum. A thumb-piece21 on the finger enables the latter to be pressed back, so as to leavethe drum 3 free to rotate. Fig. 14 illustrates a slight variation of theIIO device forintermittentlyrotating the drum 3. electrical controllingmeans at the shuttle- This consists simply of a horizontally-arrangedspring-latch 20 mounted on the co mpound shuttle-box and adapted to wipeunder the stud 19. It disengages in the same manner as the device 20.(Seen in Fig. 7.)

It is preferred that the bottom 5 of the pocket 5, which may be anysuitable shelflike or finger-like support for the shuttle, shall betilted up slightly at its front or free edge, as shown in the enlargedfragmentary view, Fig. 15, so as to better retain the shuttle in thepocket, and to tilt the shuttle a little in order that the bottom 6 ofthe cell (3 may conveniently take under the shuttle when the latter isbeing taken from the pocket 5.

Fig. 16 is a detail sectional view on a relatively large scale of theswell 17, showing how it is beveled at 17 so as to permit it to passover the side of the shuttle freely and keep the latter free from thehooked extremities of the spring-fingers 16. This view shows therelative positions of the parts.

The inclined trackway c, Fig. 5, will be, by preference, rounded oreased off at the top into the trackway 0 so as to avoid the too abruptpassage of the roller 15, and the rod or stem 8 should have on it astop-collar 8 or the like to prevent the box 13 from rising above apredetermined height.

Being the first in this field of invention, as we believe, and the firstto employ a construction wherein a compound shuttle-box, as B, isemployed at one side of a loom, the movement of which is controlled byan electric operating-circuit, and wherein the circuit connections,closed by the exhausted shuttle, are situated at the shuttle-box on theside opposite to said compound or cellular box, we do notlimit ourselvesto any specific devices or means for carrying out the object of theinvention. For example, the well-known upright magazine may be employedwith good results, and other elevating and supporting devices for thebox B might also be employed-as, for example, one of those shown in ourpending applications, Serial No. 723,128, filed July 8, 1899, and SerialNo. 7245385, filed July 19, 1899.

An important feature of our invention is the circuit-closer situatedwithin the ordinary spindle of a shuttle. This enables us to employ weftwound in the form of a cop, which is adapted to he slipped directly onthe spindle in the shuttle.

This construction is not limited to the particular weft-supplyingmechanism herein shown, being as well adapted to controlling the timesof operation of other weft-supplying mechanisms.
